BATH-TU B, BASIN, s60.

SPECIFICATION forming part of Letters Patent No. 359,169, dated March 8, 1887.

Application filed July 21, 1886. Serial No. 208,671. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAMES MoRRIsoN, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Bath- Tubs, Basins, 850., of which the following is a' specification.

The object of the invention is to prevent the foul gases escaping through the overflow-pipe of a bath or basin into the room; and it consists in providing an overflow-pipe having a valve which shall always keep the mouth of the overflow-pipe closed, except when automatically raised by the action of the water when it rises above the desired height in the basin or bath-tub.

Figure 1 is a sectional elevation exhibiting my improved overflow-pipe applied to a handbasin. Fig. 2 is an enlarged detail of a com bined waste'plug and overflow-pipe.

In the drawings, A represents a cylindrical chamber formed within or connected to the basin B. A passage, 0, constitutes communication between the lowest points in the basin B and the interior of the chamber A. At the base of the chamber A the waste or escape pipe D is connected, and immediately above the junction of the two a valve-seat, a, is formed. The valve seat a is designed to receive the check-valve E, which is preferably a cage or ordinary valve. When the valve Eis raised above the seat a, it permits the passage of the water from the bath or basin through the aperture 0 into the waste or escape pipe D. When the valve E rests on the seat a, communication between the pipeD and aperture 0 is cut off. There is a hole through the center of the valve E, anda pipe, E, is connected to and extends above the said valve E to a' point even with the high-water line in the basin B.

As the aperture connects the interior of the cylinder A with the basin B, the water in the latter will naturally flow into the chamber A when the valve E rests on the seat a. The water admitted into the chamber A can only escape when its level reaches the top of the pipe F, over which it will then flow and escape through the hole in the valve Einto the waste or escape pipe D. In order to prevent the foul gases from escaping through the pipe F, I provide a valve, G, designed to rest upon and hermetically seal the top of the pipe Fv until opened by the rising water, as hereinafter stated. I attach the valve G to a float, H, which surrounds the pipe F, as indicated. WVheuever the water reaches high-water mark in the basin B, it will of course be at a corresponding point in the chamber A, acting on the float H so as to raise the valve G and permit the water to escape by overflowing the pipe F, and the said valve will close when the water descends below the required height. Consequently the top of the pipe will always be sealed, except when water is escaping in the manner stated through the hole in the valve E into the pipe D. The pipe E, which is connected to the valve E, as before stated, passes through the float H, which float moves freely vertically, and, being connected, as shown, to the valve IE, it opens the valve G sufficiently to permit the free passage of the overflow-water through the pipe F. The top of the cylindrical chamber A is sealed by a plug, I, through the center of which a spindle, J, passes and connects with the top of the valve G. A handle is formed or attached to the spindle J, so that by pulling upon the said spindle the valve E may be raised so as to permit all the water in the basin to escape freely into the pipe D.

As the float H, valve G, pipe F, and valve E are all connected together, they may be all removed by simply unscrewing the plug I, and when thus removed may be readily cleansed.

In order to cleanse the interior of the cylindrical chamber A, I place a rubber washer or disk, K, on the pipe F at the point indicated. This washer or disk is made larger in diameter than the pipe F, so that when pulled up and down in the said pipe it will thoroughly cleanse it. I should have mentioned that a strainer, L, is placed at the mouth of the aperture or pipe 0, so as to prevent anything entering which might stop up the said aperture.

I have described my device as applied to a wash-basin; but it will be seen that it is quite as applicable to bath-tubs, sinks, &c. The only differences which would be made would be those required to connect the device to the particular water-receptacle it is applied to.

From the foregoing description it will be seen that no separate water-flow pipe is required when my device is applied; that the said device can be easily and cheaply applied; that all the parts are accessible and may be cleaned Without difficulty; that there is no possibility of sewer-gas escaping so long as the valve E is closed, and that there is no danger of a vessel overflowing which is provided with my improved device It will be observed that by placing the float around the pipe F and connecting the valves, pipe, and float, as described, the float serves to hold the valve E to its seat and also to keep the valve G down upon the top of the pipe F. Furthermore, by this construction I am enabled to use a much larger float than can be used Where the float is arranged above the valve that has its seat upon the top of the pipe, as has been proposed, thus avoiding the liability of the parts becoming inoperative and JAMES MORRISON.
